RANGE.`

SPECIFICATION forming part of Letters Patent No. 445,289, dated January 27, 1891.

Application filed September 2, 1890. Serial No. 363,764. (No model) To all when?, t may concern:

Be itknown that I, ISAAC RUBEL, a citizen of the United States, residing at Chicago, Illinois,have invented certain new and useful Improvements in Ranges, of which the following` is a specification.

The object of my invention is to make a range for cooking, in which there are two chambers or ovens, which may both be used as baking-chambers, or one used interchangeably as a baking and warming chamber, as may be desired; and my invention consists inthe features and details of construction hereinafter described and claimed.

In the drawings, lFigure l isa vertical section taken through the range from front to rear. Fig. 2 is a vertical section taken through the line i of liig. l, looking in the direction of the arrow; and Fig. l is a side elevation of a sliding` damper hereinafter described.

In making my improved range I make it with a iire-box A, and with a bakirig-chamber or oven l and a warmingchamber or oven much in the usual way. I leave a space between the two chambers, as shown in the drawings. I arrange in this space a vert-ical partition l), that begins about the center of the flue IC, which is located, as usual, at one side of the range, and carry 'it diagonaltvy back toward the rear ot' the opposite side of the range, but not far enough to reach it. In other words, I arrange a vertical partition in thespace between the chambers Band C,in elining back from about the middle of the fine to a desired distance, so as to leave a space between the end oi' the partition and the side of the range opposite the lue. lvbcginning the partition about midway of the flue a passage to the flue is secured both in the front and in the rear of the partition, which I will term the front and rear passagcsto the flue.

I arrange a sliding damper l", provided with an open space in suitablel gnidcsio permit it to be slid back and forth at the entrance of the flue, so as to respectively close or open the passage to the liuc in the front or in the rear of the partition. \\'hen the damper is moved forward, as shown in the drawings, it closes the passage to the fine in front of the partition, but leaves the passage in the rear of the partition open, and when it is moved back it opens the passage in front of the partition and closes the passage in its rear. In this way I can have one or the other of the passages open, as may be desired.

A rod II extends from the sliding damper to the back of the range to permit the damper to be adjusted back and forth. This rod also may be used to manipulate a damper I, arranged at the back of the space between the two chambers B and C, and open and eloseit in unison with the movements of the. damper F. Then the rod is pushed in to slide the damper F into its forward position to close the passage to the flue in front of the partition I), the damper I is also moved forward to close the rear end of the space between the chambers l and C,and when it is drawn back to open such passage the damper I is moved back to open the rear end of the space and to close the space J', which leads from the firebox around the chz'nnbers. lVhen the damper I is moved forward, the heat from the (ire-box can pass around back of both the chambers and down under and up in front-of the chamber C; but when it is moved back the heat is prevented from passing down under and around the chamber C and is deflected into the space between the two chambers. A damper l( is also provided in the flue near the top of the range to secure a direct draft u p the `il ue when desired.

In operation and with the damper K closed the heat from the tire-box passes along the space .I above the chamber l5 and down the back of the chamber. If the rod II be moved forward and the rearof the space between the chambers closed, and the frontl passage to the flue'be closed and the rear passage to the .due be opened, the heat will pass on down back of the chamber Gand then forward under the chamber and up in front of it and enter the space between the two chambers. As the front passage to the flue is closed, the heat passes diagonally back along the inclined partition, thus crossing the chambers toward the side opposite the tine, and then turns around the end of the partition and back across the chambers to the rear passage to the flue. In this way both chambers are fully subjected to the action of the heat and co11 verted into baking chambers. If, however, the rod I-I be drawn back and the rear end of IOO rhe space between the chambers closed, and also the space J behind the Chamber C, and the rear passage to the flue closed and the front passage to iihe flue opened, bhe heal: en ters the space between the two chambers and passes around the end of the partition and out through the front passage of the flue. In this way the Chamber B only is sufficiently heated to form a baking-chamber, and the chamber C is simply employed asa warmingehamber. I am thus able to use both chambers as baking-cham bers orto use one of them as a baking-Chamber oon vertible into a warming-chamber, as Circumstances may render necessary or desirable.

What I regard as new, and desire to secu re b v Letters Patent, is-

l. In a range,the combination of two cha-m bers, one above the other and provided with ISAAC RUBEL.
